Breast augmentation and reconstruction commonly involve a choice between two primary implant types: saline and silicone. Both utilize a shell made of solid silicone elastomer, but the filling material creates distinct differences in feel, surgical technique, and long-term maintenance. Understanding these differences is necessary for individuals considering the procedure to make an informed decision aligned with their aesthetic goals and lifestyle. This comparison focuses on their physical attributes, safety protocols, operative requirements, and financial implications.
Appearance and Texture Comparison
Silicone-filled breast implants provide a texture and consistency that closely resembles natural breast tissue. This is due to the cohesive silicone gel inside, which is thick and maintains its shape, often described with the analogy of a “gummy bear.” The density of the cohesive gel allows the implant to adapt smoothly to the body’s contours, resulting in a softer feel and a more natural-looking outcome. This structure also helps prevent the visible folding or wrinkling of the implant shell, known as rippling, which can be seen and felt in thinner patients.
In contrast, saline implants are filled with a sterile saltwater solution, giving them a distinctly different feel than silicone. Because the filling is a liquid, saline implants tend to feel firmer to the touch and less like natural fatty tissue, sometimes resulting in a more uniform or rounded appearance. The liquid nature of the internal solution can also make the edges of the implant shell more susceptible to visible rippling beneath the skin. This is especially true if the patient does not have sufficient natural tissue to mask the implant.
Differences in Safety and Monitoring
The way each implant type reacts to a shell breach dictates safety and long-term monitoring requirements. If a saline implant ruptures, the sterile salt water solution is harmlessly absorbed by the body over a few hours or days. The rupture is immediately obvious because the implant fully deflates, causing a rapid change in the size and shape of the breast. This immediate sign of failure means that no specialized imaging or routine screening is necessary for monitoring the integrity of saline implants.
Silicone implants present a different situation upon rupture, often referred to as a “silent rupture.” Modern silicone gel is highly cohesive and tends to remain contained within the fibrous tissue capsule that naturally forms around the implant, preventing noticeable deflation or immediate symptoms. Because the rupture is not outwardly visible, the U.S. Food and Drug Administration (FDA) recommends periodic imaging to detect these ruptures. Patients should undergo a magnetic resonance imaging (MRI) scan or an ultrasound starting five to six years after the initial surgery, and then every two to three years thereafter.
How Surgical Procedures Differ
The surgical requirements for placing saline and silicone implants differ primarily due to the state of the implant upon insertion. Saline implants are inserted into the breast pocket while the silicone shell is empty and deflated. Once positioned, the surgeon uses a valve to fill the implant with the saline solution until the desired volume is achieved. This technique allows for a smaller incision, often measuring between two and three centimeters, which results in less noticeable scarring.
In contrast, silicone implants come pre-filled with the cohesive gel and must be inserted into the body as a complete unit. Because the implant is already full, the surgical incision required is larger, typically in the range of four to five centimeters. This pre-filled nature also means the volume is fixed before the operation. Saline implants, conversely, offer the surgeon the flexibility to fine-tune the final volume during the procedure.
Cost and Longevity Factors
The initial financial outlay for silicone implants is higher than for saline implants, costing approximately $1,000 more per procedure. This increased upfront cost reflects the more complex manufacturing process required to produce the cohesive silicone gel and the pre-filled device. However, cost analysis must also account for the long-term maintenance required for each type.
Neither saline nor silicone implants are considered lifetime devices, and both will eventually require replacement or removal surgery. The average lifespan for both types is estimated to be between ten and twenty years. For silicone implants, the FDA-recommended periodic MRI screening adds a notable long-term expense not associated with saline implants. Evaluating the cost of replacement surgeries and the ongoing monitoring for silicone implants is important when assessing the total lifetime cost of either option.
